Description

Technical Field

[0001] The utility model relates to the technical field of rubber rings, and more specifically to a rubber ring with high sealing performance. Background Art

[0002] The rubber sealing ring is an annular cover composed of one or more parts, which is used to be installed on various mechanical equipment to perform sealing in a static or moving state at specified temperature and pressure and in different liquids and gases.

[0003] The rubber ring is generally fixed on a ring or washer of the bearing and contacts with another ring or washer or forms a narrow labyrinth gap to prevent leakage of lubricating oil and intrusion of foreign objects. When the existing rubber ring is used, the pipeline squeezes the rubber ring, causing the rubber ring to deform, thereby playing a sealing role. However, the deformation amount of the traditional rubber ring itself is limited. Excessive compression stress can easily exceed the deformation range, causing the rubber ring to produce irreversible deformation, causing the rubber ring to be damaged, and further affecting the sealing performance. Therefore, it needs to be improved. Utility Model Content

[0009] As a preferred technical solution of the utility model, there are four connecting blocks, and the top ends of the four connecting blocks are fixedly connected with a mounting plate.

[0010] As a preferred technical solution of the utility model, a fixed block located above the mounting plate is fixedly installed at the bottom of the fixed plate, a cross bar is fixedly connected between the fixed blocks, a slider is movably sleeved on the outer surface of the cross bar, a hinged rod is hinged at the bottom of the slider, and the bottom end of the hinged rod is hinged to the top of the mounting plate.

[0024] When the pipeline squeezes the inner rubber ring 1, the outer rubber ring 2 and the inner rubber ring 1 can produce elastic deformation, thereby increasing the contact area between the inner rubber ring 1 and the pipeline as a whole. At the same time, due to the design of the No. 1 elastic plate 6 and the No. 2 elastic plate 8, when the inner rubber ring 1 and the outer rubber ring 2 are squeezed, the No. 1 elastic plate 6 and the No. 2 elastic plate 8 can push the inner rubber ring 1 and the outer rubber ring 2 outward, so that the inner rubber ring 1 and the outer rubber ring 2 can fit on the outer surface of the pipeline, thereby improving the overall sealing of the inner rubber ring 1.

[0025] A sealing rubber sheet 10 is fixedly connected to the outer surface of the outer rubber ring 2 . There are three sealing rubber sheets 10 , and the three sealing rubber sheets 10 have the same size.

[0026] By providing the sealing rubber sheet 10 , when the inner rubber ring 1 is installed inside the pipeline, the sealing rubber sheet 10 can fit the inner wall of the pipeline, thereby improving the sealing effect.

[0027] The tops of the inner rubber ring 1 and the outer rubber ring 2 are movably connected to a top plate 11 , both sides of the top of the top plate 11 are fixedly installed with corrugated plates 12 , and the tops of the corrugated plates 12 are fixedly connected to a fixed plate 13 .

[0028] When the fixing plate 13 is pressed, the corrugated plate 12 will be compressed.

[0029] The top end of the outer rubber ring 2 is fixedly connected with a connecting block 14 , and the top end of the connecting block 14 penetrates the top plate 11 and is movably sleeved with the inner wall of the top plate 11 .

[0030] By providing the connecting block 14 , the movement of the connecting block 14 can drive the outer rubber ring 2 to move.

[0031] There are four connecting blocks 14 , and the top ends of the four connecting blocks 14 are fixedly connected with a mounting plate 15 .

[0032] By providing the mounting plate 15 , it is possible to prevent the connection block 14 from being separated from the interior of the top plate 11 .

[0033] Among them, a fixed block 17 located above the mounting plate 15 is fixedly installed at the bottom of the fixed plate 13, a cross bar 18 is fixedly connected between the fixed blocks 17, a slider 19 is movably sleeved on the outer surface of the cross bar 18, and a hinged rod 21 is hinged at the bottom of the slider 19, and the bottom end of the hinged rod 21 is hinged to the top of the mounting plate 15.

[0034] When the two slide blocks 19 move toward each other, the mounting plate 15 will be pushed downward through the hinge rod 21 .

[0035] The outer surface of the cross bar 18 is movably sleeved with a second spring 20 , one end of the second spring 20 is fixedly connected to the outer surface of the slider 19 , and the other end of the second spring 20 is fixedly connected to the outer surface of the fixing block 17 .

[0037] The top of the mounting plate 15 is fixedly connected with a first spring 16 , and the top end of the first spring 16 is fixedly connected with the bottom of the fixing plate 13 .

[0038] By providing the first spring 16 , the first spring 16 can push the mounting plate 15 to move downward under the action of elastic force recovery.

[0039] The working principle and use process of this utility model:

[0040] When the pipeline squeezes and pushes the rubber pad 9 upward, the inner rubber ring 1 and the outer rubber ring 2 will move upward, so that the connecting block 14 and the mounting plate 15 will move upward, and then the hinge rod 21 will be able to push the slider 19 to move outward along the outer surface of the cross bar 18, so that the second spring 20 is compressed. At this time, the second spring 20 will push the slider 19 outward under the action of elastic recovery, so that the hinge rod 21 pushes the mounting plate 15 and the connecting block 14 downward, and then the inner rubber ring 1 and the outer rubber ring 2 can push the rubber pad 9 downward, so that the rubber pad 9 fits more closely with the outer surface of the pipeline, thereby improving the fit between the overall device and the pipeline.

[0041] When the inner rubber ring 1 and the outer rubber ring 2 are squeezed, the inner rubber ring 1 and the outer rubber ring 2 will be deformed, so that the outer rubber ring 2 can push the sealing rubber sheet 10 outward, so that when the inner rubber ring 1 is installed as a whole inside the pipe, the sealing rubber sheet 10 can fit the side of the pipe more closely. When the inner rubber ring 1 and the outer rubber ring 2 are squeezed, the No. 1 elastic plate 6 and the No. 2 elastic plate 8 will be squeezed and deformed, and then the No. 1 elastic plate 6 and the No. 2 elastic plate 8 will push the inner rubber ring 1 and the outer rubber ring 2 outward under the action of elastic recovery, so that the outer surfaces of the inner rubber ring 1 and the outer rubber ring 2 can fit closely to the outer surface of the pipe, thereby improving the sealing effect and at the same time increasing the deformation of the inner rubber ring 1 and the outer rubber ring 2, thereby increasing the overall service life of the inner rubber ring 1.
